Method and device for predicting radar echoes

Abstract

The embodiment of the invention discloses a method and device for predicting the radar echoes. According to one specific embodiments of the invention, the method comprises the steps: responding to receive a radar echo chart sequence, carrying out the pre-screening operation of the radar echo chart sequence, and determining the radar echo chart sequence after pre-screening operation as a first radar echo chart sequence; inputting the first radar echo chart sequence into a pre-trained radar echo prediction model to obtain a first prediction result, wherein the first prediction result comprises aradar echo chart sequence in a set time period in future, and the radar echo prediction model employs an end-to-end neural network structure. According to the embodiment of the invention, the methodand system can improve the accuracy of the predicted radar echo chart sequence through the radar echo prediction model employing the end-to-end neural network structure.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, and in particular to a method and device for predicting radar echoes. Background technique [0002] In weather forecasting scenarios, short-term weather forecasting is an important link and an important supplement to long-term weather forecasting. Among them, the short-term weather prediction can refer to the prediction of the weather (such as strong convective weather such as thunder and lightning, strong wind, hail, heavy rainfall, etc.) within a short period of time (such as the next half hour, 1 hour, 3 hours, etc.) in the future in a specific area. Usually, short-imminent radar echo prediction is required before short-imminent weather prediction. [0003] At present, the radar echo prediction methods are generally based on the optical flow method and the linear extrapolation method based on statistics. The optical flow method generally calculates the sparse fe...

Problems solved by technology

However, due to the complex and changeable cloud motion information, there are problems such as cloud layer synthesis and dissipation, so the prediction results obtained by using the existing radar echo prediction methods are generally low in accuracy
